Here is another golf tip from Golf Magazine:
I CAN'T BELIVE I JUST POPPED UP MY TEE SHOT
WHY YOU DID IT
You slid your left shoulder-and,thus,the bottom of your swing arc-in front of the ball on your downswing, so the clubhead was still descending when it contacted the ball.
MAKE SURE YOU DON'T DO IT AGAIN
Move your left shoulder-and the bottom of your swing arc-back where they belong. It's easy to do if you use the fixes below and keep your left shoulder even with the back of the ball on your downswing.
- Tee the ball higher so that the bottom of the ball is even with the top of your clubhead
- Play the ball two inches inside your left heel and tilt your spine to the right at address.
- Try to keep your tee in the ground through impact-think of sweeping the ball off the peg.
